3. The vein which drains the blood from the intestine to the liver.
4. Blood vessels carrying blood to the left Atrium.
5. The blood vessel which supplies blood to the liver.
6. Squeezing out of white blood cells from the capillaries into the surrounding tissues.
7. The relaxation phase of the heart .
8. The compound formed when hemoglobin combines with carbon dioxide in blood.
Answers
Answer:
Explanation:
1.When white blood cells encounter invaders such as bacteria, they engulf and destroy them through a process called phagocytosis
2.Closure of the atrioventricular valves results in the first heart sound, S1. As pressures in the ventricles continue to rise together in a normally functioning heart, they eventually reach a critical threshold pressure at which the semilunar valves (pulmonary valve and aortic valve) open.
3.The portal vein or hepatic portal vein (HPV) is a blood vessel that carries blood from the gastrointestinal tract, gallbladder, pancreas and spleen to the liver. This blood contains nutrients and toxins extracted from digested contents.
4.the pulmonary veins bring oxygen-rich blood to the left atrium. The aorta channels oxygen-rich blood to the body from the left ventricle.
5.The liver receives the oxygen and nutrients it needs in blood that comes from two large blood vessels: Portal vein. Hepatic artery.
6.The walls of these tiny blood vessels are very thin and are composed of overlapping endothelial cells which allow nutrients and waste to pass through. Red blood cells can squeeze through the capillaries one at a time, as shown on the left. White blood cells can freely pass through the walls of a capillary.
7.The cardiac cycle refers to the alternating contraction and relaxation of the myocardium in the walls of the heart chambers, coordinated by the conduction system, during one heartbeat. Systole is the contraction phase of the cardiac cycle, and diastole is the relaxation phase.
8.carboxyhaemoglobin. a stable compound produced when carbon monoxide combines irreversibly with HAEMOGLOBIN in the red blood cells, giving the blood a bright red colour. A consequence of the reaction is that haemoglobin is less able to combine freely with oxygen
Answer:
1 phagosytosis is the process 2 lub and hub are the sounds 3 hepatic portal vein 4 pulmonary artery 5 hepatic artery sorry I couldn't understand question 6 7 diastolic is the phase 8 carbaminohimoglobin is the compound I hope it is helpful and plz mark me as brainlist answer and also follow me I am new on brainly thanku
