11.3 Data response by shiva sharma https://padlet.com/nee_shiva/Excretion Made with a wish on a star en-us 2018-05-08 00:56:57 UTC 2026-01-23 19:48:37 UTC hello@padlet.com Sam wvnsekoh https://padlet.com/nee_shiva/Excretion/wish/260314213 1)There is much more blow flow rate in the kidney compared to the other organs, 420.0 ml min^-1 100g^-1 in kidney, compared to 87 min^-1 100g^-1 in heart muscle, 54 min^-1 100g^-1, 13 min^-1 100g^-1 in skin and 2.7 min^-1 100g^-1 in resting skeletal muscle

2) one liter of blood in kidney 1000/420 = 2.38 Min
oxygen delivered in kidney
2.38 x 84 = 199.92 = 200L (3s.f.)

one liter of blood in brain
1000/54 = 18.5 Min
oxygen delivered in brain
18.5 x 10.8 = 199.8 = 200L (3s.f.)

one liter of blood in skin
1000/13.0 = 76.9 Min
oxygen delivered in skin
76.9 x 0.5 = 38.45 = 38.5L (3s.f.)

4) The kidney is used as a means of removing all toxic waste products in the blood before being excreted as urine. Hence in order to ensure that all the toxic waste products are properly removed from the body, the kidney would have to filter large amounts of blood in order to completely remove all the toxic waste, hence causing the blood flow of kidney to be significantly higher than the other organs

5) Selective reabsorption

6) when moved to a cold environment, thermoregulation occurs which causes the rate of blood flow in skin would increase due to the vasodilation of the blood vessels in the skin surface in order to release body heat to keep the body warm. Hence blood flow would increase, allowing the person to have faster blood flow in the skin.

The highest rate of blood flow is in the Kidney and the next highest rate is in the Heart muscle. Next is the brain and then the skin. The lowest rate of blood flow is in the skeletal muscle.

2. Oxygen delivered to organ:
Brain:
1 minute: 54ml
1000/54ml = 18.5 minutes
18.5minutes: 10.8 x 18.5 = 199.8ml

Skin:
1 minute: 13ml
1000/13ml = 76.9minutes
76.9minutes: 2.6 x 76.9 = 199.9ml

Skeletal Muscle:
1 minute: 2.7ml
1000/2.7ml = 370.4minutes
370.4minutes
= 0.5 x 370.4 = 185.2ml

3.
4. The kidney's main function is to filter the toxins in the blood.

5. Selective Reabsorption
6. Due to the cold, the body would have to focus more on thermoregulating the body and therefore, there will be a higher blood flow to the skin.

The blood flow to the Kidney is the largest as compared to the rest of the organs, at 420 ml/min100g. While the blood flow to the brain, skin, resting skeletal muscle and heart muscle are 54.0, 13.0, 2.7 and 87.0 ml/min100g respectively.

2. kidney = 200.0 ml
heart muscle = 200.0 ml
skeletal muscle = 185.2 ml
skin = 200.0 ml
Brain = 200.0 ml

3. skin = 14.6%
skeletal muscle = 36.0%
heart muscle = 63.2%
kidney = 8.1%

4. The kidney has the highest rate of blood flow of all the organs at, 420.0 ml/ min100g. The toxins are transported to the kidney from all other organs therefore more blood is transported to the kidney so that the toxins can be excreted. The heart has the second highest blood flow at 87.0 ml/min100g. While for the other organs, blood is transported to them to provide oxygen for aerobic respiration to occur.

5. Selective reabsorption: active transport - require energy - higher oxygen consumption - increased rate of aerobic respiration

6. Heart: More blood would flow to the heart as to provide more oxygen so that the heart can undergo a higher rate of aerobic respiration so that the heart can pump faster. This will increase the metabolic activity of the body thus providing more heat energy to the body, hence increasing the overall temperature of the body. ]]> 2018-05-14 02:21:30 UTC https://padlet.com/nee_shiva/Excretion/wish/260314242 Birdie birdie1 https://padlet.com/nee_shiva/Excretion/wish/260314256 1) The rate of blood flow to Kidney is dramatically higher than other organs with the staggering 420 ml per minute per 100g.

2) Kidney = 1000/420 = 2.38 minutes. 2.38 x 84 = 200 ml of oxygen delivered in 1 litre.

3) Skin= 2.6x0.34= 0.884 ml used
skeletal muscle = 0.5x0.34 = 0.17ml
Heart muscle = 17.4x0.34 = 5.916ml
Kidney = 84x0.34 = 28.56 ml

4) the demand for oxygen in different organs are different as skin will have less activity than heart muscle. Heart muscle need a lot of oxygen to pump blood to the rest of the body, so much more oxygen is demanded.
In the skeletal muscle at the resting state, it does not requires much because it is static. When physical exercise starts, the oxygen demand will increase drastically.

5) Selective reabsorption. In a cold environment, the blood flow to the skeletal muscle, heart, skin increase because thermoregulation to keep the temperature constant. ]]> 2018-05-14 02:21:33 UTC https://padlet.com/nee_shiva/Excretion/wish/260314256 Kaitlyn https://padlet.com/nee_shiva/Excretion/wish/260314304 1. The blood flow for the kidney is much more than the other organs. The kidney's blood flow is nearly 200 times the resting skeletal muscle.
2. The kidney receives 420ml per minute; in
3. skin - 14.6%
skeletal muscle - 36%
heart - 63.2%
kidney - 8.1%
4. The kidney filters blood from all parts of the body, all the blood would have to flow through the kidney, thus, it had high blood flow. However, the percentage of oxygen consumption in the kidney is the lowest out of all the organs because there is very little use for oxygen in the kidney. However, for the heart, it oxygenates blood and needs aerobic respiration for ATP to pump blood, thus, a large amount of oxygen is needed.
5. Selective reabsorption
6. In a cold country, a person would have higher blood flow as the skin has to thermoregulate to make sure the body is warm enough. ]]> 2018-05-14 02:21:53 UTC https://padlet.com/nee_shiva/Excretion/wish/260314304 geraldine https://padlet.com/nee_shiva/Excretion/wish/260314441 1. The rate of blood flow to the kidney is much higher than the other organs at 420.0ml/min/100g.

2. Brain: 10.8 x (1000/54) = 200
Skin: 2.6 x (1000/13) = 200
Skeletal muscle: 0.5 x (1000/2.7) = 185

4. The function of the kidney is to filter out metabolic waste that is toxic out from the blood. Hence, blood from all parts of the body must be passed through the kidney for the removal of toxins such as urea, leading to the highest volume of blood flowing to the kidney compared to other organs.

5. Selective reabsorption.

6. The blood flow to the skin would increase for the sake of thermoregulation, where the body responds to the cold temperatures through vasoconstriction occurring in the blood vessels under the skin. ]]> 2018-05-14 02:22:09 UTC https://padlet.com/nee_shiva/Excretion/wish/260314441 Faize https://padlet.com/nee_shiva/Excretion/wish/260314449 1) The rate of blood flow to kidney is the highest with 420.0 ml per minute per 100g of tissue while the rate of blood flow to the skeletal muscle is the least with just 2.7 ml/min for 100g of tissue. There is also moderate amount of rate flow of blood in heart and brain with 87.0 and 54.0 ml/ min/ 100g respectively. While skin has a relatively lower amount of rate of flow of blood when compared to heart and brain.

Q4)
Kidney has the highest blood flow rate and this is due to the fact

Q6)
Selective reabsorption
The blood flow to the skin would change when the person is shifted to a colder environment. This is due to the fact that in the cold more blood would flow to the skin so as to enable thermoregulation. When we are too cold, the blood vessels supplying warm blood to the skin becomes constricted. This reduces heat loss.

2. The kidney receives 420ml per minute. In 2.38 minutes, 1l is delivered to 100g of tissue. Thus, 84 x 2.38 = 200ml of oxygen is delivered.
