What is the main substance of blood?
Plasma is the main component of blood and consists mostly of water, with proteins, ions, nutrients, and wastes mixed in. Red blood cells are responsible for carrying oxygen and carbon dioxide. Platelets are responsible for blood clotting.
What are two substances in blood?
The composition of blood
| Component | Function(s) |
|---|---|
| Plasma | Transporting carbon dioxide, digested food molecules, urea and hormones; distributing heat |
| Red blood cells | Transporting oxygen |
| White blood cells | Ingesting pathogens and producing antibodies |
| Platelets | Involved in blood clotting |
What is a chemical substance in blood?
These substances include electrolytes (such as sodium, potassium, and chloride), fats, proteins, glucose (sugar), and enzymes. Blood chemistry tests give important information about how well a person’s kidneys, liver, and other organs are working.
What are the substance present in both urine and blood?
Urea is the chief nitrogenous end product of the metabolic breakdown of proteins in all mammals and some fishes. The material occurs not only in the urine of all mammals but also in their blood, bile, milk, and perspiration.
What substances are found in blood plasma?
Important constituents include electrolytes such as sodium, potassium, chloride, bicarbonate, magnesium, and calcium. In addition, there are trace amounts of other substances, including amino acids, vitamins, organic acids, pigments, and enzymes.
What are the substances present in blood and urine?

What are the six Substances transported by blood?
The blood transports oxygen, carbon dioxide, nutrients, water, hormones, waste substances and heat.
Why is blood considered to be fluid connective tissue?
Since these living cells are suspended in plasma, blood is known as a fluid connective tissue and not just fluid. Blood absorbs oxygen from the lungs and transports it to different cells of the body. The waste carbon dioxide moves from the blood to the lungs and exhaled.
Where do all the cells in the blood come from?
All of the cells found in the blood come from bone marrow. They begin their life as stem cells, and they mature into three main types of cells— RBCs, WBCs, and platelets. In turn, there are three types of WBC—lymphocytes, monocytes, and granulocytes—and three main types of granulocytes (neutrophils,…
What kind of substances are found in plasma?
In addition to proteins, plasma contains a wide variety of other substances. These include various electrolytes, such as sodium, potassium, and calcium ions; dissolved gases, such as oxygen, carbon dioxide, and nitrogen; various organic nutrients, such as vitamins, lipids, glucose, and amino acids; and metabolic wastes.
