what are the general characteristics of blood?

In humans, blood is an opaque red fluid, freely flowing but denser and more viscous than water. The characteristic colour is imparted by hemoglobin, a unique iron-containing protein. Hemoglobin brightens in colour when saturated with oxygen (oxyhemoglobin) and darkens when oxygen is removed (deoxyhemoglobin).

It has four main components: plasma, red blood cells, white blood cells, and platelets. Blood has many different functions, including: transporting oxygen and nutrients to the lungs and tissues.

['they give the lungs a really big surface area.', 'they have moist, thin walls (just one cell thick)', 'they have a lot of tiny blood vessels called capillaries.']

The liquid part, called plasma, is made of water, salts, and protein. Over half of your blood is plasma. The solid part of your blood contains red blood cells, white blood cells, and platelets. Red blood cells (RBC) deliver oxygen from your lungs to your tissues and organs.

The cells of the blood are important because they are a readily accessible population whose morphology, biochemistry, and ecology may give indications of a patient's general state or clues to the diagnosis of disease.

The primary objective of the blood is to maintain a constant environment for the rest of the body's tissues. It maintains this homeostasis via its viscosity (thickness), its ability to carry dissolved substances, and its ability to move to all body parts.

Blood has three main functions: transport, protection and regulation. Blood transports the following substances: Gases, namely oxygen (O2) and carbon dioxide (CO2), between the lungs and rest of the body.

Erythrocytes are red blood cells that travel in the blood. Their characteristics of being red, round, and like rubber give them the ability to complete their specific functions. They carry oxygen from the lungs to the body, and bring carbon dioxide back to the lungs to be expelled.

Fortunately, biologists have developed a list of eight characteristics shared by all living things. Characteristics are traits or qualities. Those characteristics are cellular organization, reproduction, metabolism, homeostasis, heredity, response to stimuli, growth and development, and adaptation through evolution.

Red blood cells (erythrocytes) The red blood cells are highly specialized, well adapted for their primary function of transporting oxygen from the lungs to all of the body tissues.

Blood is a heterogeneous mixture because the blood cells are physically separate from the blood plasma. The cells have different properties than the plasma. The cells can be separated from the plasma by centrifuging, which is a physical change.

Those characteristics are cellular organization, reproduction, metabolism, homeostasis, heredity, response to stimuli, growth and development, and adaptation through evolution. Some things, such as a virus, demonstrate only a few of these characteristics and are, therefore, not alive.

Blood is made up of red blood cells, platelets, and different kinds of white blood cells. Our bone marrow continuously makes new red and white blood cells. The lymphatic system consists of the bone marrow, the spleen, the thymus (in young people), and lymph nodes.

The three formed elements of blood are: white blood cells (leukocytes), red blood cells (erythrocytes) and platelets (thrombocytes ).

About red blood cells Red blood cells contain hemoglobin. Hemoglobin is an iron protein that carries oxygen to all body parts. When red blood cell levels are too low, the body parts do not get enough oxygen.
