Answer:

Blood is a body fluid in humans and other animals that delivers necessary substances such as nutrients and oxygen to the cells and transports metabolic waste products away from those same cells. In vertebrates, it is composed of blood cells suspended in blood plasma. Plasma, which constitutes 55% of blood fluid, is mostly water, and contains proteins, glucose, mineral ions, hormones, carbon dioxide, and blood cells themselves. Albumin is the main protein in plasma, and it functions to regulate the colloidal osmotic pressure of blood. The blood cells are mainly red blood cells, white blood cells and platelets. The most abundant cells in vertebrate blood are red blood cells. These contain hemoglobin, an iron-containing protein, which facilitates oxygen transport by reversibly binding to this respiratory gas and greatly increasing its solubility in blood. In contrast, carbon dioxide is mostly transported extracellularly as bicarbonate ion transported in plasma.

Explanation:

more simple:  

the red liquid that circulates in the arteries and veins of humans and other vertebrate animals, carrying oxygen to and carbon dioxide from the tissues of the body.

Chronic obstructive pulomonary diseases (COPD), include:
KIM [24]

Answer:

The correct answer to the question: Chronic Obstructive Pulmonary diseases (COPD), include:____, would be, D: a and b are correct.

Explanation:

COPD, or best known as Chronic Obstructive Pulmonay Disorder, is the general name given to a disease in which the lungs are incapable of performing their task of oxygen and carbon dioxide exchange, because of an obstruction either of the airways, or the alveoli, which are the sacks in which the actual exchange takes place. This obstruction can happen either because of an overproduction of mucus, or because the airways become fibrous, and therefore, oxygen cannot be exchanged. The other reason is when the alveoli are damaged and destroyed and air sacks form in the lungs. In COPD, we have two types: Chronic Bronchitis, in which due to continuous coughing, and mucus production, the bronchi become inflamed and fibrous and therefore exchange is much more difficult. In the second form, we have emphysema, in which the constant coughing starts affecting the lining of the alveoli, until it can literally be destroyed and pockets of air can form inside the actual lung tissue.
