BELL WORK:Copy the question and your answer

Which of the following correctly describes an interaction that occurs between two body systems that helps a rabbit outrun a pursuing coyote?

A. The skeletal system releases additional calcium, and the circulatory system retains more sodium in the blood to provide muscles with ions for contraction.

B. The digestive system increases the rate of digestion, and the excretory system ceases to provide tissues with more nutrients.

C. The respiratory system increases the breathing rate, and the circulatory system increases blood pressure to provide tissues with more oxygen.

D. The endocrine system releases hormones that prepare the immune system to deal with possible injuries.

CO: I will examine and describe how the reproductive system interacts with other systems.

LO: I will finish my vocabulary project. I will write notes and talk

with a partner.

•Sexual Reproduction–In humans, the reproductive system produces, stores, and releases specialized sex cells known as gametes. –Gametes are released to create the fusion of sperm and egg to form a zygote, the single cell from which all cells of the human body develop.

Sexual Reproduction

Sexual Development

• Puberty is a period of rapid growth and sexual maturation during which the reproductive system becomes fully functional.

• When puberty ends, reproductive organs are fully developed.

• Puberty usually begins between the ages of 9 and 15, and usually starts one year earlier in females than in males.

Reproduction HormonesHormone: Produced by: Function:

Testosterone Testicles Triggers male sex traits

Follicle-stimulating hormone (FSH)

Pituitary Stimulates egg/sperm development

Stimulates estrogen

Luteinizing hormone (LH) Pituitary Stimulates Testosterone

Regulates the release of egg, corpus luteum, progesterone

Estrogen Ovaries Triggers female sex traits

Progesterone Corpus luteum Maintains Uterus lining

The Male Reproductive System

• Function of the male reproductive system: To produce & deliver sperm

The Male Reproductive System• A sperm cell consists of:

• a head, which contains the nucleus

• a midpiece, which contains energy-releasing mitochondria

• a flagella, which propels the cell forward

Head

Nucleus

Midpiece

Mitochondria

Diseases and Disorders of the Male Reproductive System

Disease/Disorder DescriptionProstate cancer Most common form of cancer in men over

40; risks of developing it increase with age

Prostatitis Inflammation of the prostate gland; may be acute or chronic

Testicular cancer Malignant growth in one or both testicles; more common in males 15–30 years; more aggressive malignancy

The Female Reproductive System• Functions of the female reproductive system:

1. To produce eggs2. To nourish and support a developing embryo

• Ovaries: primary reproductive organs– The ovaries are located in the abdominal cavity.

The Menstrual Cycle• Menstrual cycle: when an egg develops and is

released from an ovary– The uterus is prepared to receive a fertilized egg. – If the egg is fertilized, it is implanted in the uterus and

embryonic development begins. – If the egg is not fertilized, it is discharged.

• The menstrual cycle is controlled by internal feedback mechanisms between the reproductive system and the endocrine system. The cycle takes an average of 28 days.

The Menstrual Cycle

*Most females menstruate during the first 3-7 days of the cycle.

Diseases and Disorders of the Female Reproductive System

Disease/Disorder Description

Breast cancer Second leading cause of cancer deaths in women; classified as stage 0 to 4

Cervical cancer Slow to develop; Pap smear detects abnormal cervical cells

Cervicitis Inflammation of the cervix usually due to an infection

Dysmenorrhea Condition with severe menstrual cramps limiting normal activities
