Chapter 5: Excretion in Humans- A Quick Revision

The aim of this chapter in the Class 7 Biology Syllabus for the ICSE Board is to help the students learn the definition, need, and significance of the term excretion. The outcome of the chapter is to make the students identify the spots on the human body where the organs of the excretory system lie i.e., at the back of the abdomen at the level of the 11^th and the 12^th ribs for the kidneys, etc. and infer the functions of the kidney. Students are taught how the process of excretion occurs in the body and about the substances that are excreted such as urine, feces, and their components such as urea, uric acid, water, bile pigments, salts like sodium, magnesium, and chloride, etc.

The students also learn about the other modes of excretion of waste products from the body apart from the urinary bladder and rectum that are the skin and lungs which expel sweat containing salts and carbon dioxide respectively from the body.

FAQs on Concise Biology Class 7 ICSE Solutions for Chapter 5 - Excretion in Humans

1. How does the Kidney participate in the formation of urine as described in Class 7 ICSE Biology Chapter 5?

According to chapter 5 of Class 7 ICSE biology, the process of urine formation begins when the blood enters the kidney at the glomerulus. Water and other small solutes get filtered in the Bowman’s capsule and the filtrate passes through the thin walls of the capsule into the renal tubule. As the filtrate passes through the renal tubule water and other small solutes get reabsorbed and the remaining liquid is passed out as urine with other wastes generated by the body.
