Functions of the heart by https://padlet.com/anthony_scotland/bolrfq846lbr NCFE LESSON RESOURCES en-us 2019-01-09 12:19:53 UTC 2023-02-07 10:15:12 UTC hello@padlet.com Jord n Matt https://padlet.com/anthony_scotland/bolrfq846lbr/wish/2462747763 The valves connected to the right side of the heart are called the tricuspid and pulmonary valve.
The valves connected to the left side of the heart are called the bicuspid, aorta and mortal valve.
Left side of the heart receives oxygenated blood from lungs.
Right side of the heart receives deoxygenated blood.
The septum is a thick tissue muscle that separates the left and right side of the heart it helps blood flow through the blood vessels. 
The aorta is the main artery that carries your blood from your heart around your body it leaves through the aortic valve the red blood cells carry oxygen in the blood to the lungs. carbon dioxide is then released and blood flows back to the heart through the veins.

The left atrium receives the now oxygen-rich blood from the lungs and pumps it into the left ventricle. The left ventricle pumps the oxygen-rich blood to the body through a large network of arteries.]]> 2023-01-31 10:13:20 UTC https://padlet.com/anthony_scotland/bolrfq846lbr/wish/2462753425 Fin and Ellie https://padlet.com/anthony_scotland/bolrfq846lbr/wish/2462756331
There are 4 chambers in your heart with the left and right atrium and left and right ventricle.
The arteries take blood away from the heart. They have a thick and elastic walls and are high in pressure. They have a small lumen. 
Your veins take blood back to the heart and carry deoxygenated blood. They have thin walls and have thin walls and a larger lumen. 
Capillaries are found in the tissue and it is a sight of gaseous exchange and they have a very thin wall.

The heart works as a double circulatory system system. The right hand side connects deoxygenated from the body and then pumps it through the lungs.
The left handside collects oxygenated blood from the heart and pumps it round the body.]]> 2023-01-31 10:15:54 UTC https://padlet.com/anthony_scotland/bolrfq846lbr/wish/2462756331 Sami & Nathaniel https://padlet.com/anthony_scotland/bolrfq846lbr/wish/2462767175 Functions Of The Heart

Structure of the heart
The heart is roughly the size of your fist and is positioned slightly to the left of the chest. There are 4 chambers that make up the heart - 2 to the left and 2 to the right. The two smaller lower chambers are called the atria while the two larger upper chambers are called the ventricles. These two sides are seperated by a small thin wall of muscle called the septum.

Circulatory system
The heart pumps blood, about five litres, all around the body all the time. This is called circulation. The heart, blood and blood vesseles make up the cardiovascular system. The right side of the heart recieves blood that is low in oxygen because it has all been used by the brain and body, and then pumps it to the lungs, where it picks up a fresh supply of oxygen. The blood then returns to the left side of the heart, ready to be pumped back out to the brain and the body.

Blood vessels
The blood is pumped all around the body through a network of blood vessels. Arteries carry oxygen-rich blood from your heart to all parts of the body. They get smaller the further away they are from the heart. Capillaries connect the smallest arteries to the smallest veins, and help exchange water, oxygen, carbon dioxide and other nutrients between the blood and the tissues around them. Veins carry blood, lacking in oxygen, back towards your heart, and get bigger as they get nearere the heart. Blood vessels are able to widen or narrow depending on how much blood each part of your body requires.

Valves
The heart has four valves. They act like gates, keeping the blood moving in the right direction. The aortic valve and the mitral valve are on the left side. the pulmonary valve and the tricuspid valve are on the right side.

From the COVID-19 pandemic to a recovering world, more and more fans have been taking to platforms like Instagram and TikTok. There, they banter and discuss their favourite sports topics, especially when they can’t attend games or events in person.

This will force oxygen both in and out the lungs. 

Intercostal muscles contract
Diaphragm contacts
Chest cavity gets larger

Intercostal muscle relaxes 
Diaphragm relaxes 
Chest cavity gets smaller and pressure increases in lungs ]]> 2023-02-07 10:15:12 UTC https://padlet.com/anthony_scotland/bolrfq846lbr/wish/2471508035
