What are the general characteristics of the lungs?
The lungs are responsible for the intake of air, and distributing the air and it's properties to the rest of the body, as well as filtering it and taking out harmful substances. The mucus membranes that line the nose, mouth, throat have mucus that traps dirt and foreign matter that we may breathe in. Tiny hairs (cilia) beat back and forth to quickly filter out any junk allowing us to breath in freash air.

Urinary tract infections are much more common in men or female and why?
Urinary tract infections are usually caused when bacteria that normally live in our digestive system get into the bladder the nearness of the female urethral opening to the vagina and rectum
The usual site of implantation for the fertilized egg is the:
When the fertilized egg attaches itself to the uterine wall The egg is fertilized in the outer part of the fallopian tube. Implantation occurs in the upper third of the uterus. Implantation sometimes can cause bleeding or minor spotting.
Which one of the following alimentary segments is no for digestive function, only food conduction:
The esophagus, rectum and anus
The main function of the male testes is:
Primary function of the male reproductive system is reproduction
The middle part of the male urethra that extends from the prostate gland to the penis is called the:
Function of milky colored fluid secreted from the prostate gland:
To resist the acidity of the vagina
Which one is not part of the male reproductive duct system:
epidymus B) ductus deferens
C) urethra D) prostate
What is not true about Urethra?
What is not true about Urethra?
A) Extends from the base of the urinary bladder to the tip of the penis
B) Carries both urine and sperm
C) Sperm enters from the ejaculatory duct
D) Male has shorter than female****
Which one is not a region of the urethra?
A) Prostatic urethra -surrounded by prostate
B) Membranous urethra - from prostatic urethra to penis
C) Spongy (penile) urethra - runs the length of the penis
D) Bulbo urethra- runs around bulbourethral ****
The advantages of accessory gland secretions are the following, except:

Functions of urinary system are:
The urinary system is a network of filters, tubes and containers that cleanse the body of excess salts, fluids, waste and electrolytes that enter the body through food and liquids.
Internal and external urethral sphincters
When either of these muscles contract, the urethra is sealed shut. The internal sphincter is a continuation of the detrusor muscle and is made of smooth muscle, therefore it is under involuntary or autonomic control. The external sphincter muscle of urethra in males is a secondary sphincter to control the flow of urine through the urethr, is made of skeletal muscle
Origins and functions of female and male organs; explain
Male and female have comparable organs to produce the reproductive cells and hormones they need for reproduction. In men, the externally located testicles produce the predominant male hormone testosterone and produce sperm cells. Women have internal gonads called ovaries, which produce the female hormones, estrogen and progesterone and the female gametes, eggs.
Internal and external respiration; explain
Internal Respiration includes all processes involved in exchanging O2 to CO2 between the body and the environment. Involves moving air in and out of the lungs (inhaling & exhaling respiratory Movements) Primary Function-meeting the respiratory demands of cells. External respiration refers to the exchange of gas (CO2 and O2) between the lungs (alviolo) and blood (pulminary capilaries)
