Fitness 🏄🏽♀️, Reproduction🤰 ,Menstruation 🩸 Flashcards
What does it mean to be a fit person?
They can do moderate exercises,
And no increase in breathing
What is the difference we can observe from an unfit and fit person when exercising
FIT people can do more exercises like running, and UNFIT people rest longer
How much did person a a pulse rate increase from resting to directly after exercise?
14(48-34)
Which person could you say is the fittest
Person A
Give a reason why you said person a
Quickest recovery, lowest increase in heart rate from resting pulse to directly after exercise lowest heart rate
Find out how long person b takes to return to their resting pulse rate
Make the time longer than seven minutes that you take your reading for
Find out how person a takes to return to their resting pulse rate
Change the time to every minute
Why do this effects make it more difficult to exercise?
Oxygen and glucose cannot get to the muscles quickly
Being overweight, due to your diet has certain complications give three examples
Example number one the extra mass of the body means that more energy is needed to move it around. Example number to the heart has to work much harder to push blood around the larger body. Example number three the space inside the arteries, mega narrower, because fat deposits, build up inside them.
Explain why professional sports men eat plenty of protein on most days and carbohydrates just before the match
There is plenty of protein to build and maintain muscle. They eat carbohydrates before message to provide energy.
Name four components of cigarettes that influence the person negatively, and state what he does to the body
Nicotine-is addictive, make a blood cells narrower, which increases blood pressure. Tar -is a carcinogen that causes lung cancer. Particulates-it damages, long tissue, decreases gaseous exchange in the lungs, carbon monoxide-combines with hemoglobin in the red blood cells and the red blood cells carry less oxygen.
Explain why smokers find it difficult to stop smoking
It’s addictive people crave cigarettes, people K cigarettes, if they’ve gone without it for a long time person could become agitated because they’ve gone through withdrawal
Where is professional sportsman and sportswoman? Do not smoke explain why.
Smoking damages the lungs, less oxygen is taken to the muscles. Less energy is released. The sports person is at a disadvantage.
Some smoke low tar cigarettes, cigarettes discuss whether or not this is a good idea
No, it is not better if you smoke Lothar cigarettes, you still get tied into your body is still developed lung cancer, overtime light cigarettes do not reduce all the health risks it lowers lung cancer, but not the other
What are gametes
Reproductive cells formed by organisms for sexual reproduction
Name two types of gametes are formed in humans
Male sperm cell female egg cells
How many chromosomes does a human body cell have?
46
How many chromosomes does a human gamete have?
23
Explain your previous answer
Meiosis half’s the chromosome count this prevent double of chromosomes after fertilization
Name the special p process, made to make gametes
Meiosis
Where do gametes get made?
Female-egg is made in woman’s ovaries mail-sperm is made in males testicles
What is fertilization?
Fusion of male and female gametes used to form a zygote
What prevents more than one cells from fertilizing the same egg cell?
As soon as one sperm passes through the eggs, cell membrane, the memory changes in does not allow any other sperm cells through
Give the function of the vagina
Acts as a birth control. Semen is deposited.
Function of the cervix
The opening between the vagina and the uterus
Uterus
Place where baby develops
Endometrium
Where embryo undergoes implantation
Fallopian tubes
Transport egg cell to uterus . Where fertilization occurs
Ovary
Realest egg cell . Releases hormones progesterone and o estrogen
Penis
Acts as a copulatin organ. Deposit semen into vagina
Urethra
Transport semen out of the male body
Testis
Produce sperm and hormones testosterone
Sperm duct
Transport from the epididmes
Epidemes
Place where sperm is stored and matures
Prostate gland
Release substances that nourishes
Seminal vesicle
Release substance that protect the sperm
What is the difference between sperm and semen?
Sperm are gametes produced from the testis semen secretions from the seminal ves vesicle and prostate gland, added to it
What happens after fertilization of the egg cell
An egg leave the ovary. The egg is fertilized in the fallopian tubes. It’s now called a zygote . The zygote divides into a smallball of cells now called an embryo. The embryo enters the uterus and attaches to the lining, and starts to develop into a feotus
Conception
Fusion of male and female gametes
Pregnant
When the feotus has successfully implanted the endometrium
Implantation
When the embryo attaches to the uterus lining
Ovulation
When the egg cell is released from the ovary (day 14 of the ms)
2) The flow diagram the development of the new life.
egg cell
zygote
Embryo
Feotus
Egg cell - female gamete released from ovary
Zygote -substance that relsults from a fertilized egg
Embryo -is a developed a zygote consisting of plus minus 32 cells
Feotus- develop embryo with visible lumps and heartbeat
What happens if you use not fertilized
1 An egg cell develops in an ovary. The lining of the uterus starts to grow thicker.
2 The egg cell is released from the ovary. The lining of the uterus becomes thick and spongy.
3 The egg cell was not fertilised, so it just travels on into the uterus and dies.
4 The thick, spongy lining of the uterus breaks down and is lost through the vagina.
What is the menstrual cycle?
»
The monthly pattern of the thickening and loss of the uterus lining is called the menstrual cycle.
Period
The loss of the uterus lining through the vagina is called menstruation, or a period.
How many people die early of smoking
4.2 million
The World Health Organization estimates that:
Smoking kills half of the people who smoke cigarettes
Smoking skills more people than all deaths from car crashes, drugs and HIV/AIDS
