Can be veins, can be arteries, can be capillaries, can be the aorta..
The veins carry blood toward the capillaries.
blood travels from the ascending aorta to the aortic arch to the descending aorta
Yes
Yes, the highest in the aorta and larger elastic arties, and decreses as the arteries branch and blood travels farther from the heart.Blood pressure drops significantly in the arterioles and steadily decreses through capillaries, venules, and veins, and drops to zero in the right atrium.
R.b.c
Capillaries
Unoxygenated blood travels to the heart though the veins to be pumped to your lung capillaries. At you lung capillaries the blood becomes oxygenated and then goes back to the heart to pump oxygenated blood to the rest of your body. the capillaries blood travels though you arteries.
arterioles
The blood leaves the heart through the aorta, the largest artery in the body. From there, it travels to smaller arteries and arterioles, ultimately reaching the capillaries where oxygen and nutrients are exchanged with tissues.
The left ventricle of the heart pumps blood into the aorta. From there, it travels to all body tissues.
Veins are where the blood flow is the slowest. Blood flow velocity decreases from the aorta to the arteries to capillaries.
