Looking at a stained smear of horse blood and seeing a leukocyte with large red granules in its cytoplasm. I am most likely seeing a granulocyte, an eosinophil in particular.

Leukocytes are white blood cells and there are various types of white blood cells including granulocytes, agranulocytes.

Granulocytes are white blood cells present with granules and produced in the bone marrow. There are three types of granulocyte; they include eosinophil, basophil and neutrophil.

Eosinophils are white blood cells with large granules and they stain red with dye. Their nucleus is also made up of two unsegmented lobes.

What are the blood vessels that carry blood to and from the lungs?

Answer · 5 votes

To expand on Dr. Herman’s answer. The pulmonary artery, originating in the right ventricle, carries deoxygenated blood from the heart to the lungs (most other arteries, though, carry oxygenated blood), to be oxygenated in the lungs. The pulmonary veins, terminating in the left atrium, carries oxygenated blood (most other veins, though, carry deoxygenated blood) from the lungs to the heart, to be distributed to the rest of the body.

Which blood vessels carry blood away from the heart?

Answer · 0 votes

Arteries & Veins. Explanation: The ARTERIES are major blood vessels connected to your heart. 1. The pulmonary artery carries blood from the right side of the heart to the lungs to pick up a fresh supply of oxygen. 2. The aorta is the main artery that carries oxygen-rich blood from the left side of the heart to the body. 3. The coronary arteries are the other important arteries attached to the heart. They carry oxygen-rich blood from the aorta to the heart muscle, which must have its own blood supply to function. The VEINS also are major blood vessels connected to your heart. 1. The pulmonary veins carry oxygen-rich blood from the lungs to the left side of the heart so it can be pumped to the body. 2. The superior and inferior vena cavae are large veins that carry oxygen-poor blood from the body back to the heart.

Answer · 3 votes

A blood vessel carrying blood from the lungs to the heart is pulmonary vein. There are four pulmonary veins, two from each lung that drains into the left atrium of the heart. Pulmonary veins are responsible for carrying oxygenated blood from the lungs back to the left atrium of the heart. This differentiates the pulmonary veins from other veins in the body, which are used to carry deoxygenated blood from the rest of the body back to the heart.So, the correct answer is 'Pulmonary vein'.

a cockroach is a fast-moving insect. how can an animal with an open circulatory system be so speedy?

Answers

An animal like a cockroach with an open circulatory system is so speedy because in these organisms tracheal system delivers oxygen throughout the body.

What is an Open circulatory system?

An open circulatory system may be characterized as a type of circulatory system in which blood vessels are completely absent and blood generally flows freely through the cavities of the body. This type of circulatory system is present in arthropods.

Due to the absence of blood vessels, the flow of blood is extremely high in animals that have an open circulatory system. Apart from this, in cockroaches, oxygen is carried out through the tracheal system because of the absence of the lungs. So, it makes the process so speedy.

Therefore, an animal like a cockroach with an open circulatory system is so speedy because in these organisms tracheal system delivers oxygen throughout the body.

Answers

The sodium channel possesses an inactivation gate that temporarily closes after the channel is active.

In neurons, sodium channels are responsible for the ascending phase of the action potential (depolarization).

Characteristically, this channel has two transmembrane voltage-dependent gates.

When the membrane is depolarized to the threshold, both gates are activated, but since one of them opens rapidly while the other closes slowly, the channel remains open for less than 2-5 milliseconds.

Therefore, we can conclude that the sodium channel is responsible for the depolarization and possesses two gates which one temporarily closes after the channel is active.
