Once the blood reaches the lungs, the alveoli in the lungs, or tiny air sacs, capture the carbon dioxide from the blood and transfer it to the lungs where it is released upon exhalation. Other critical organs are involved in the excretory system other than the lungs, the New Health Guide Organization points out.


The lungs also play a role in excretion. Lungs excrete carbon dioxide and water vapor by diffusion and exhalation. HUMAN URINARY SYSTEM. Some of the body’s excretions leave by way of the urinary system. The urinary system consists of the kidneys, ureters, urinary bladder, and the urethra (Figure 11-2). The kidneys are bean-shaped organs that ...


Excretion is a process by which metabolic waste is eliminated from an organism. In vertebrates this is primarily carried out by the lungs, kidneys and skin. This is in contrast with secretion, where the substance may have specific tasks after leaving the cell. Excretion is an essential process in all forms of life.

When amino acids are used for energy. What is the largest organ. blood (which is liquid tissure) Lungs.the lungs take off amino groups, destorys worn out red blood ...


Excretion is the process of removing metabolic wastes. In the lungs, oxygen diffuses in to the capillaries, and carbon dioxide, a byproduct of cellular respiration, diffuses out.


Drug excretion is the process of eliminating a drug from the body. A drug, which is either biologically active itself or a prodrug, may be excreted in its original chemical state. Alternatively, all or a portion of a drug may undergo chemical modification and be eliminated as biologically active, or inactive, metabolites (see the record on Drug Biotransformation).


The lungs use cells known as alveoli to remove the carbon dioxide from our blood. Otherwise, the carbon dioxide would accumulate and have a detrimental effect to our body. Accessary Excretory System Organs 1. Liver. Although considered a secondary, or accessary excretory system organ, the liver plays a vital part in keeping the body clean.


Define excretion. excretion synonyms, excretion pronunciation, excretion translation, English dictionary definition of excretion. ... such as carbon dioxide and urea, resulting from metabolic processes. Higher animals have specific organs of excretion, such as the lungs and kidneys. In plants and many lower organisms, waste is eliminated by ...


Excretion - Methods of waste disposal: Disposal of metabolic and nonmetabolic wastes involves both active and passive mechanisms. In general, gaseous wastes are eliminated through passive mechanisms without the direct expenditure of energy on the part of the living system. The solid and liquid waste-disposal mechanisms used by higher animals are active (energy consuming) systems that separate ...


The excretory system is the system of an organism's body that performs the function of excretion, the bodily process of discharging wastes. The Excretory system is responsible for the elimination ...
