Human Reproductive System Anatomy

In the diagram, which structure stores and transports mature sperm from the testes before joining the vas deferens?

• Urethra running through the penis

• Seminal vesicles behind the bladder

• Prostate gland below the bladder

• Epididymis coiled on each testis

Using the diagram, which pathway correctly traces sperm from production to exit from the body?

• Seminal vesicles → prostate → vas deferens → urethra

• Testes → urethra → epididymis → vas deferens

• Epididymis → testes → vas deferens → urethra

• Testes → epididymis → vas deferens → urethra

Which structure is the primary site of sperm production?

• Seminiferous tubules in testes

• Prostate gland ducts

• Epididymis storage region

• Urethra passageway

A student claims nutrient-rich seminal fluid is made in the testes. Which correction best explains the actual source?

• Produced mainly by urethral walls

• Secreted by epididymal tissue

• Generated by sperm midpiece

• Made by accessory glands

Which structure is the site of egg production and hormone secretion shown in the diagram?

• Uterus lining and muscular wall

• Fallopian tube or oviduct

• Cervix opening into uterus

• Ovary with developing follicles

An egg released from the ovary must travel through which structure to reach the uterus?

• Cervical canal during dilation

• Fallopian tube connecting to uterus

• Endometrium within uterine cavity

• Vaginal passage and birth canal

Based on the labeled diagram, which structure directly connects the ovary to the uterus for egg transport?

• Oviduct

• Urethra

• Cervix

• Vagina

A sperm cell fuses with an egg cell. What chromosome number results in the zygote after fertilization?

• Twenty-three pairs duplicated

• Forty-six pairs condensed

• Forty-six chromosomes total

• Twenty-three chromosomes total

Around 30 hours after fertilization, what event typically occurs first in the developing zygote?

• Implantation into the uterus

• Cleavage forming the morula

• First mitosis and cell division

• Differentiation of germ layers

Human development from fertilization to birth is divided into three About how long is a trimester?

• approximately 3 months

• approximately 6 months

• Approximately 30 days in each trimester

• 100 days per trimester precisely
