Figure 18.2.2 18.2. 2: Structure of Blood Vessels. (a) Arteries and (b) veins share the same general features, but the walls of arteries are much thicker because of the higher pressure of the blood that flows through them. (c) A micrograph shows a similarly sized artery and vein.

Sep 4, 2024 · Circulatory System. Your circulatory system, or cardiovascular system, supplies oxygen and nutrients to your whole body and removes waste through your blood. Your heart pumps blood that flows through your arteries, veins and capillaries. These blood vessels and your heart form your circulatory system.

You need continuous blood flow through your heart and body to stay alive. Your heart is a powerful muscle that pumps oxygen-rich blood out to your body. Once it leaves your heart, this blood flows through many blood vesselsto reach every part of your body, from the major organs (like your brain) to the smallest tissues at the tips of your toes. You...
Your heart has four chambers, which you can think of like rooms in your home. Two are on the right side of your heart (right atrium and right ventricle), and two are on the left side (left atrium and left ventricle). Your blood flows through all four chambers — just not all in a row. Like returning home after a long day at work, your blood returns ...
The right and left sides of your heart work together to make sure blood flows throughout your whole body. Blood flows through your heart in a series of steps. These steps take place in the space of one heartbeat — just a second or two.
Your heart pumps oxygen-rich blood through your aortic valve and into your aorta. Your aorta is your body’s main artery, and it has many branches that go in different directions to reach various areas of your body. Picture a tree with one main trunk (your aorta) and lots of branches (all the arteriesthat connect to your aorta). Your aorta and its b...
Here are some things you can do to support healthy blood flow: 1. Reach and keep a weightthat’s healthy for you. 2. Eat a heart-healthy diet. 3. Exercisefor about 150 minutes per week (that’s 30 minutes, five days a week). 4. Limit alcoholintake. 5. Manage stress with healthy coping techniques such as talk therapy or meditation. 6. Quit smokingor u...
Blood clots, or clumps of blood that form inside veins or arteries. Clots block blood flow and can lead to deep vein thrombosis (DVT), pulmonary embolism, stroke or occlusion of an artery. High blood pressure, or hypertension, occurs when there’s too much force against the walls of your arteries.
Venules and veins. Blood flows from the capillaries into very small veins called venules, then into the veins that lead back to the heart. Veins have much thinner walls than do arteries, largely because the pressure in veins is so much lower. Veins can widen (dilate) as the amount of fluid in them increases.
Arteries transport blood away from the heart and branch into smaller vessels, forming arterioles. Arterioles distribute blood to capillary beds, the sites of exchange with the body tissues. Capillaries lead back to small vessels known as venules that flow into the larger veins and eventually back to the heart.

Oct 31, 2023 · Figure 40.12.1 40.12. 1: View of the heart: This front view of the heart shows the direction of blood flow to and from the heart. Blood leaves the heart through the pulmonary artery and aorta, while blood enters the heart through the two venae cavae and pulmonary veins. The slow rate of travel through the capillary beds, which reach almost ...
