Arteries carry oxygenated blood away from the heart and typically have ________________ blood pressure. Veins carry deoxygenated
KatRina [158]
The correct answer is high, low.

Arteries are part of the circulatory system and are responsible for carrying blood away from the heart and around the body. The arterial blood is oxygenated and this process ensures that every tissue around the body will receive oxygen and nutrients through this blood flow.

Veins are also part of the circulatory system and are responsible for carrying the deoxygenated blood from the tissues back to the heart.

Venous pressure is much lower than the arterial pressure. More specifically, venous pressure ranges from 5 to 8 mmHg, while arterial pressure ranges from 15 to 30 mmHg.

What types of antigen do T cells NOT recognize? What types of antigen do T cells NOT recognize? self-antigens bacterial antigens
Stolb23 [73]

Answer:

Self-antigens are not recognized and attacked by the T cells.

Explanation:

In immunology, the antigens are those substances which are bound by the antibodies. The antigens can be originated from within the bodies, known as self antigens or from outside the body, known as non-self antigens. The immune system identifies and attacks non-self invaders or the foreign harmful objects present in the body. It does not attack the self-antigens under the normal conditions. This is due to the negative selection of T cells of the thymus.
