B. Spleen
C. Pancreas
D. Liver

Answer 1

Blood could be a body fluid in humans and alternative animals that delivers necessary substances like nutrients and chemical elements to the cells and transports metabolic waste merchandise away from those self-same cells. Invertebrates, it's composed of blood cells suspended in plasma.

Complete solution:
The kidneys filter concerning one-quarter (750-1000 pints) of the blood that's output by the guts daily. This blood is distributed to the body's filter treatment plant, wherever it's refined by the kidneys and circulated on to the remainder of the body. a number of the blood flow becomes fluid waste (1/1000th to 2/1000th) and is distributed into the bladder for storage till it may be handily expelled. This waste is termed as urine.

Hence the right answer is choice A.

Additional information:
Kidney- The kidneys are a combination of bean-shaped organs on either facet of your spine, below your ribs and behind your belly. every excretory organ is concerning four or five inches long, roughly the scale of an oversized fist.
The kidneys' job is to filter your blood. They take away wastes, manage the body's fluid balance, and keep the proper levels of electrolytes. All of the blood in your body passes through them many times daily. Blood comes into the excretory organ, waste gets removed, and salt, water, and minerals are adjusted if needed. The filtered blood goes back to the body. Waste gets changed into excretion, that collects within the kidney's pelvis - a funnel-shaped structure that drains down a tube known as the epithelial duct to the bladder.

Note:
Each excretory organ has around 1,000,000 little filters known as nephrons. you could have only 100 percent of your kidneys operating, and you'll not notice any symptoms or issues. If blood stops flowing into an excretory organ, half or all of it may die. which will cause kidney disease.
