right side:
Blood enters the heart through two large veins, the inferior and superior vena cava emptying oxygen-poor blood from the body to the right atrium.
atrium contracts, blood flows from your right atrium into your <em>right ventricle</em> through the open tricuspid valve.
ventricle contracts, blood leaves the heart through the pulmonic valve, into the <em>pulmonary artery</em> and to the lungs where it is oxygenated.
left side:
<em>pulmonary vein</em> empties oxygen-rich blood from the lungs into the <em>left atrium</em>.
contracts, blood flows from your left atrium into your <em>left ventricle </em>
ventricle contracts, blood leaves the heart through the aortic valve, into the<em> aorta </em>and to the body.
veins carry blood to the heart ( deoygenated blood)
Arteries carry blood from heart ( oxygen rich blood)
Capillaries connects them.
<span> cells maintain homeostasis as they are living things. The main way cells maintain homeostasis is through their cell membranes. Cell membranes protect the cell from the outside world, if there is too much of something in the cell, the cell membrane uses pockets to expel some of it, it trasports nutrients across the cell, and it also dictates what goes in and out of the cell. Those are some ways a cell maintains homeostasis. And all living things must maintain homeostasis</span><span>: <span>Regulate intracellular ion control (e.g. maintain very specific [Ca^2+] levels)
Regulate extracelluar to intracellular ion transport. E.g. for maintaining water and blood pressure via the kidneys.
Regulate metabolism, for temperature control (e.g. in brown adipose tissue).
Regulate transcription and translation, for hormone release and
