Respiratory System and Digestive System - Prof. Sideris, Assignments of Biology

Various aspects of the respiratory system and the digestive system. It includes questions and answers about the functions, structures, and processes of these two important body systems. The respiratory system section covers topics such as gas exchange, the role of the nasal conchae, the respiratory center in the nervous system, and the mechanics of inhalation and exhalation. The digestive system section explores the passage of food through the digestive tract, the ph changes along the tract, and the absorption of nutrients. The document also includes a crossword puzzle and a concept map related to the respiratory and digestive systems, as well as a discussion about the urinary system and the male and female reproductive systems. Overall, this document provides a comprehensive overview of these key physiological systems and could be useful for students studying biology, anatomy, or related subjects.

The function of the nasal conchae is to increase the surface area of
the nasal cavity, which helps to warm, moisten, and filter the air as
it is inhaled.

Complete the following discussion about the urinary system, using the words in the word bank below.

Ureters water/fluid nephrons acid-base semen

Exterior incontinence 20 4 micturition

Peristalsis external urethral urinary bladder nitrogenous

The kidney is referred to as an excretory organ because it

excretes 1 wastes. It is also a major homeostatic organ because

it maintains the electrolyte,

2 , and

3 balance of the blood.

Urine is continuously formed by the structural and functional

units of the kidneys, the 4 , and is routed down the 5 by the

mechanism of

6 to a storage organ called the

7

. Eventually,

the urine is conducted to the body 8 by the urethra. In the

male, the urethra is 9 centimeters long and transports both

urine and

10

. The female urethra is

11 centimeters long and

transports only urine.

Voiding or emptying the bladder is called 12. Voiding

has both voluntary and involuntary components. The voluntary

sphincter is the 13 sphincter, composed of skeletal muscle.

An inability to control this sphincter is referred to as 14.

Answer the following questions.

  1. What tissue lines the urinary bladder?
  2. What hormone regulates the formation and concentration of urine?
  3. Where do the following processes predominantly occur in the urinary system:

a. Filtration

b. Reabsorption

c. Secretion

  1. What materials are normally found in urine?

a. ______________________________________

b. ______________________________________

c. ______________________________________
