P: Vein

b)

c) systemic capillaries : oxygen diffuses into the body cells and carbon dioxide diffuses  into the capillaries                                      Gill capillaries : oxygen dissolves into the gills while carbon dioxide diffuses into the environment

# data[].attributes.body
d) single, closed circulatory system because blood flows through the heart only once in a complete circulation and the blood is contained within closed blood vessels

2) a) P Vena cava
Q Aorta
R Pulmonary artery
S Pulmonary vein
B)

# data[].attributes.body
c) Coronary Artery. the effect is, nutrients and respiratory gases couldn't be transferred to the heart cells, such as cardiac muscles, which will cause the cells to stop functioning or die. This will cause heart failure.

c)
Gill capillaries: oxygen diffuses into capillaries. Carbon dioxide diffuses out

Systemic capillaries: oxygen diffuse into the tissue while carbon dioxide diffuses from the tissue into the capillaries.

d) Closed circulatory system. It is because in fish, blood is always contained in a continuous closed blood vessel and is disteibuted to the whole body. The exchange of oxygen and nutrients also occurs across the wall of blood  capillaries.

d) The heart has valves

Essay Question
a) i) X is artery and Y is vein because in vessel X , blood flows towards the body cells while in vessel Y, blood flows away from the body cells. This shows the transfer of oxygenated blood in vessel X which represents the artery and the transfer of deoxygenated blood in vessel Y which represents the Vein

a) M: artery N: venctricle O: Atrium P: vein
b) clockwise rotation
c) gill capilaries: deoxygenated blood gain oxygen and release carnon dioxide. Thus turning into oxygemated blood
Systemic capilaries: oxygen from oxygenated blood diffuse into the tissues and the carbon dioxide diffuse into the blood cells.
d) Single circulatory system because the blood flow in only one direction.

# data[].attributes.body
ii)-X has small lumen while Y has a large lumen
- X has a thick, muscular and elastic wall while Y has a thin, less muscular and less elastic wall
- X has no valves while Y do
- blood flows at high pressure in X while in Y, it flows at  a very low pressure
- X transfers oxygenated blood while Y transfers deoxygenated blood
- The direction of blood flow in X is from the heart to the whole body while in Y is from the whole body to the heart

Answer for Question 2

c) Pulmonary vein. If it is blocked, it will block oxygen from entering the heart muscle cell and cause diseases like Pulmonary Vein Stenosis. This will later cause coughing up blood (hemoptysis) and limit the patient's ability to do daily stuff activities.

d)The biscupid valve ensures that blood flows into the right ventricle does jot flow back to the right atrium while triscupid valve ensures that blood which flows into the left ventricle does not flow back into the left atrium.

# data[].attributes.body
a) i. X is pulmonary artery and y is pulmonary vein. it is because bloods enter the lung through pulmonary artery and leaves the lung through pulmonary vein

a) ii. The differences between blood vessel X and Y are blood vessel X carry oxygenated blood, however blood vessel Y carry deoxygenated blood. Futhermore, blood vessel X has high pressure due to smaller diameter of cappilary compare to blood vessel Y which has bigger diameter of cappilary at a low pressure.

b
Z has thin walls as thick as one cells. It allow the exchange of gasses to occur between blood and cell through diffusion

C) coronary artery. Clogged coronary artery causes oxygen deficit that can lead to heart failure

D) Veins contain valve to ensure one-way flow of blood

Essay
A i) X is artery because the blood flow is downward and y is vein because the blood flow is upward

ii) characteristic for artery :

- has thick , muscular and elastic wall
- does not have valve except for semilunar valve at the base of aorta and base of pulmonary artery
- high blood pressure

while characteristic for veins :

- has thin , less muscular and less elastic wall
- contain valves to mantain one way flow of blood
- very low blood pressure

b) Thin walls of z  that is one-cell thick enables effective gaseous exchange. Secondly it is not muscular because the blood pressure is low

Z has a thin wall which is one cell thick which ease the diffusion of nutrients. Moreover, the dense network of Z increases the surface area for nutrient diffusion significantly.
