A beating heart contracts and relaxes.
Step five is that blood is sent to the lungs to be oxygenated. Step six is the blood leaves the lungs and travels back towards the heart via the pulmonary veins. Step seven is blood enters the left atrium. Step eight is the blood passes the bicuspid valve and enters the left ventircle.
2018-12-13 · Arteries are vessels that carry blood away from the heart. The main pulmonary artery or pulmonary trunk transports blood from the heart to the lungs. While most major arteries branch off from the aorta, the main pulmonary artery extends from the right ventricle of the heart and branches into left and right pulmonary arteries. Cardiac muscle has a rich supply of blood, which ensures that it gets plenty of oxygen.
Blood enters the heart through the atria. Blood from two vena cavae enters the right atrium. Blood from the pulmonary veins enters the left atrium.The atria fill, followed by the ventricles. Blood
From here, blood moves through a series of increasingly smaller arteries, until it reaches a capillary, the junction between arteries and veins. Here oxygen molecules detach from the red blood cells and slip across the capillary wall into body tissue. Now de-oxygenated, blood begins its return to the heart. For example, high levels of "bad" cholesterol in your blood can be a sign that you're at increased risk of having a heart attack. And other substances in your blood can help your doctor determine if you have heart failure or are at risk of developing fatty deposits (plaques) in your arteries (atherosclerosis).
What type of blood flows through the Superior
When the valves work properly, blood flows in only one direction. Both sides of the heart work together to ensure there is always an adequate supply of oxygen-rich blood available to the rest of the body. On the right side of the heart, oxygen-poor blood enters through the inferior and superior vena cava before emptying into the right atrium.

(a) The name of the blood vessels are; 1 - Pulmonary vein 3 - Hepatic portal vein 6- Hepatic vein 7 -Posterior vena cava (ii) Coronary arteries supply blood to the heart with oxygen. (iii) 2. Aorta. (iv) 4 (Renal artery) 5 (Renal vein) 1. Thick muscular wall2. Narrow lumen 3. Valves absent 1. Thin muscular walls.2. Wide lumen3. Valves are present
From the capillaries, blood passes into venules, then into veins to return to the heart. Arteries and arterioles have relatively thick muscular walls because blood Blood flow is a pulse wave that moves out from the aorta and through the arterial branches, then is reflected back to the heart. Learning Objectives. Explain the The right side of the heart pumps blood to the lungs to pick up oxygen.

Functions of Heart and blood Vessels 1. The heart is an essential pumping organ in the cardiovascular system where the right heart pumps deoxygenated blood (returned from body tissues) to the lungs for gas exchange, while the left heart pumps oxygenated blood (returned from the lungs) to tissue cells for sustaining cellular respiration. 2.
2021-01-20 6. Heart chambers: hollow cavities within the heart for containing blood. • Two smaller chambers called atrium are near the base, and two larger chambers called ventricle are close to the apex. • Right Atrium (RA) after receiving deoxygenated blood from body tissues through the superior and inferior vena cava, pumps the blood About the Heart and Blood Vessels. The heart is the hardest working muscle in the human body. Located almost in the center of the chest, a healthy adult heart is the size of a clenched adult fist. By age 70, the human heart will beat more than 2.5 billion times.
